The physics
Real physics, explained plainly. Each piece answers one question a nine-year-old might ask at the dinner table, in language a parent or a teacher can hand straight over, written by the author of The Measure.
- Is there really a down?Down feels like the most obvious direction there is — until you notice that it points somewhere different for everybody.5 min readIn The Measure, learning to stop trusting down is the first thing that makes Koby good at the sport.
- Why do a hammer and a feather fall at the same speed?Heavy things do not fall faster than light things. Air is the whole reason it looks like they do.5 min readIn The Measure, everyone on the pitch falls at exactly the same rate, and the game is about what you do with that fact.
- Do you actually move the Earth when you jump?You push the planet exactly as hard as it pushes you. The difference is what happens next.5 min readIn The Measure, that equal-and-opposite push is not a footnote — it is the whole sport.
- Why does distance matter so much to gravity?Move twice as far away and the pull does not halve — it drops to a quarter. That one detail decides how orbits, tides and falling all behave.5 min readIn The Measure, height is never just height — every metre you gain changes what the pull underneath you is worth.
- Why would you be weightless at the centre of the Earth?The middle of a planet sounds like the strongest place for gravity. It is actually the one place with none at all.4 min readIn The Measure, the pull is never a single fixed number — where you are standing decides what it is worth.
- Could Drop actually work?A sport played on ground that will not hold still, where every push you give is a push you get back. Most of it is real. One part is not.5 min readThe Measure takes the honest half of this seriously and never lets a player off the hook for the rest.
